| 摘 要： | 设计了S波段的MILO，工作频率为2.33 GHz，器件不容易产生模式竞争，适合于单模运行。进一步对MILO进行改造：阴极加入端面发射，使磁绝缘效果更好；收集极采用金属薄膜，利用磁绝缘电流形成虚阴极，充分发挥负载电流的磁绝缘作用，利用负载电流参与波束能量转换，使输出功率和效率进一步提高。通过优化设计的虚阴极MILO，在输入电压为450 kV，电流为45 kA时，最终得到2 GW的周期平均输出功率，效率高达10%。

| Abstract: | An S-band MILO was designed by 2D particle-in-cell(PIC) electromagnetic code, based on the L-band hard-tube MILO of the Philips laboratory. The working frequency of the S-band MILO was 2.3 GHz. The design was further improved to increase the output power and efficiency. The emission increase from the cross section resulted in better magnetic insulation. A metal film was used to replace the conductor so that the load current, which had only supplied magnetic insulation, could be used to participate in the wave-beam energy transformation. The average output power in a period was 2 GW when the input voltage was 450 kV and the input current was about 45 kA. The efficiency was up to 10%. |
